BG LIFT, a leader in the compact crawler crane sector, has filed three innovative new patents for compact cranes that revolutionize lifting in tight and complex spaces, enhancing both safety and efficiency. These cutting-edge solutions place the company at the forefront of industry innovation and directly address the practical needs of operators.
Sensitive, Precise, and Responsive Hydraulic Control
Among the three new patented innovations is the T4000 hydraulic crane, designed for installation on four-axle trucks. This system delivers performance comparable to that of conventional mobile cranes, while offering greater operational efficiency, flexibility, and movement precision.
The crane is equipped with an advanced hydraulic circuit featuring up to three load-sensing pumps: one driven by the truck’s internal combustion engine and two electric pumps. This setup allows operations even in enclosed environments, such as industrial facilities, without starting the truck engine—reducing energy consumption and emissions.
A specially configured hydraulic distributor ensures dynamic fluid flow management and immediate response to commands. The flow rate adjusts based on specific movement needs, ensuring precise maneuvers and a high level of control, even in challenging working environments.
Additionally, the separation between the crane control system and the stabilizer system eliminates the risk of interference, preventing simultaneous operations that could compromise stability and thus enhancing overall safety during use.
Hydraulic Device with Synchronized Activation
The new M100 crawler crane features an advanced hydraulic system that optimizes both boom movements and tracked mobility, adapting efficiently to various job site conditions.
The machine is powered by two engines—one internal combustion and one electric—each paired with two hydraulic pumps. This configuration enables flexible power management based on operational requirements.
The hydraulic circuit is divided into two independent distributors: one dedicated to controlling the tracks and winch, and the other to boom functions (lifting, extension, rotation).
A key technical element is the presence of an intelligent electrovalve that, when there are no active boom commands, automatically redirects flow to the track motors.
This allows the full capacity of all four pumps to be used for movement, increasing travel speed and improving overall operational efficiency.
Controlled Side Rotation Without Stabilizers: The M100 E Pushes the Limit to 180°
The M100 E battery-powered crawler crane is designed to overcome the main operational challenges of traditional machines—especially during lateral operation.
The system combines an advanced hydraulic architecture with next-generation electronic control, enabling a working angle of up to 180° while ensuring maneuverability even in confined spaces.
The design includes an active stability control system based on an integrated sensor network:
- Pressure sensors to monitor load on the cylinders
- Rotation sensor to detect boom angle
- (On applicable models) Track distance sensor
The data is processed in real time by dedicated software that dynamically adjusts lifting and movement operations based on detected stability conditions.
With the tracks fully extended and the boom within an angle of approximately 25°, the machine can move loads in pick and carry mode under safe operating conditions.
When the boom exceeds this angle, static lifting and lowering operations up to 90° in both directions are still possible, with load limits automatically managed by the system.
The crane is powered by an electric motor driving a fixed-displacement hydraulic pump—a solution that reduces noise, consumption, and emissions while optimizing operating costs.
The entire system has been developed to meet the demanding requirements for reliability, safety, and flexibility on the most challenging construction sites.
